Why Pushing Changes Fetal Oxygenation
The fetal heart rate does not need to remain perfectly unchanged during a contraction.

REx-PN
The fetal heart rate does not need to remain perfectly unchanged during a contraction. The more useful question is whether it recovers between contractions and whether the pattern suggests adequate fetal oxygen reserve. Early decelerations may accompany head compression, whereas persistent late or complicated variable decelerations require action. For the RPN, the priority is to recognize a change in context: active pushing, contraction frequency, maternal position, oxytocin infusion, and the fetal heart rate pattern must be interpreted together. Stop pushing and reposition promptly when a concerning deceleration persists, then escalate through the RN and obstetric team according to local policy and scope.
